The line 976

$img = new Securimage_ctf();

in plugins/si-contact-form/includes/class-fscf-process.php should be

$img = new Securimage_Captcha_ctf();

since the class Securimage_ctf doen not exist anymore in captcha/securimage.php, it is replaced with class Securimage_Captcha_ctf

Got it fixed ??

Breaks captcha on PHP 5.4.45-0+deb7u2 giving the false url of /contact/#FSContact1 instead of correct thank-you page redirect after submitting form.

Logs reveals an error
PHP Fatal error: Class 'securimage_ctf' not found in /var/www/blog/wp-content/plugins/si-contact-form/includes/class-fscf-process.php on line 977

The line in is class-fscf-process.php (captcha with PHP sessions)
$img = new Securimage_ctf();

Worked before the update, nbothing else is changed.
